TECHNICAL FIELD

The present invention relates to stable, preferably clear, aqueousodor-absorbing compositions (solutions), articles of manufacture, and/ormethods of use, not including use directly on human skin, comprisingsolubilized water-soluble uncomplexed cyclodextrin and, preferably, awater-soluble antimicrobial preservative for said aqueous cyclodextrinsolution. The odor-absorbing compositions are designed to control odorscaused by a broad spectrum of organic odoriferous materials, which may,or may not, contain reactive functional groups, and to preferably remainshelf stable for a substantial period of time. Preferably, the aqueousodor-absorbing composition is for use on inanimate surfaces, especiallyfabrics, and more specifically, clothes, in order to restore and/ormaintain freshness by reducing malodor without the need for washing ordry cleaning.

BACKGROUND OF THE INVENTION

The present invention relates to stable, preferably clear, aqueous odorabsorbing compositions, articles of manufacture and/or method for use onsurfaces, not including use directly on human skin, as an odor-absorbingcomposition. Such compositions can optionally provide a "scent signal"in the form of a pleasant odor which signals the removal of the malodor.Preferably, the compositions are sprayed onto fabrics, particularlyclothes, to restore their freshness by reducing malodor without washingor dry cleaning. The compositions are preferably not used directly onhuman skin because the preferred preservative may cause skin irritation.Fabrics treated with some preferred compositions of the presentinvention can also optionally provide release of fragrance uponrewetting, such as when the wearer perspires. This phenomenon providesan added benefit to fabrics treated with the composition of the presentinvention in that the fabrics will stay fresher longer.

A wide variety of deodorizing compositions are known in the art, themost common of which contain perfumes to mask malodor. Odor masking isthe intentional concealment of one odor by the addition of another. Thecontrol of odor on fabrics, in particular clothes, has been accomplishedby using perfumes, colognes, etc. However, preference to perfume isgreatly varied and high levels are needed to ensure that the malodor isno longer noticeable.

Odor modification, in which the odor is changed, e.g., by chemicalmodification, has also been used. Current malodor modification methodsknown in the art are oxidative degradation, which uses oxidizing agentssuch as oxygen bleaches, chlorine, chlorinated materials such as sodiumhypochlorite, chlorine dioxide, etc., and potassium permanganate toreduce malodor, and reductive degradation which uses reducing agentssuch as sodium bisulfite to reduce malodor. Both of these methods areunacceptable for general use on fabric because they can damage coloredfabrics, specifically, they can bleach and/or discolor colored fabrics.

Other methods of odor control utilize actives that are targeted to reactwith malodors having specific chemical functional groups. Examples ofsuch actives are; biguanide polymers, which complex with organiccompounds containing organically bound N and/or S atoms and fattyalcohol esters of methyl methacrylic acid which react with thiols,amines, and aldehydes. Such actives are limited in the scope ofprotection which they afford because they only react with limited typesof malodor. A more detailed description of these methods can be found inU.S. Pat. Nos.: 2,544,093; 3,074,891; 4,818,524; and 4,946,672; and U.K.Pat. App. No. 941,105, all of said patents and applications incorporatedherein by reference.

Other types of deodorizing compositions known in the art containantibacterial and antifungal agents which regulate the malodor-producingmicroorganisms found on the surface to which the deodorizing compositionis directed. Many skin deodorant products use this technology. Thesecompositions are not effective on malodors that have already beenproduced and malodors that do not come from bacterial sources, such astobacco or food odors.

Fabric malodor is most commonly caused by environmental odors such astobacco odor, cooking and/or food odors, or body odor. The unpleasantodors are mainly organic molecules which have different structures andfunctional groups, such as amines, acids, alcohols, aldehydes, ketones,phenolics, polycyclics, indoles, aromatics, polyaromatics, etc. They canalso be made up of sulfur-containing functional groups, such as, thiol,mercaptan, sulfide and/or disulfide groups.

It is preferable to apply an odor absorbing material, preferably a broadspectrum odor absorbing material, to fabrics rather than a masking orchemical reaction material for odor control between washing and drycleaning operations. As opposed to a masking or chemical reactionmaterial, odor absorbing material can eliminate a broad spectrum ofodoriferous molecules and usually does not contribute an odor of itsown. The commonly known solid odor absorbers such as activated charcoaland zeolites can be harmful to fabrics and therefore are not preferredas an odor controlling agent under these circumstances. Activatedcharcoal easily stains light colored fabrics and zeolites are seen as alight colored stain on dark colored fabrics. Furthermore, the zeolitescan cause a "harsh" feel if too much is deposited.

Uncomplexed cyclodextrin molecules, which are made up of varying numbersof glucose units provide the absorbing advantages of known absorbentdeodorizing compositions without harmful effects to fabrics. The currentteachings in the art suggest that cyclodextrin does not contribute tothe growth of microorganisms despite the fact that they are made up ofvarying numbers of glucose units. See Effect ofHydroxypropyl-B-cyclodextrin on the Antimicrobial Action ofPreservatives, S. J. Lehner, B. W. Mailer and J. K. Seydel, J. Pharm.Pharmacol 1994, 46:p.188 and Interactions Between P-Hydroxybenzoic acidEsters and Hydroxypropyl-B-Cyclodextrin and Their Antimicrobial EffectAgainst Candida Albicans, S. J. Lehner, B. W. Muller and J. K. Seydel,International Journal of Pharmaceutics, 1993, 93, pp. 201-208. It hasbeen discovered, however, that cyclodextrin is a prime breeding groundfor certain microorganisms, especially when in aqueous compositions.This growth problem leads to a problem with storage stability ofcyclodextrin solutions for any significant length of time. Contaminationby certain microorganisms, can cause microbial growth resulting in anunsightly and/or malodorous solution. Because microbial growth incyclodextrin solutions can occur, it is preferable to include awater-soluble antimicrobial preservative, which is effective forinhibiting and/or regulating microbial growth, to increase storagestability of clear, aqueous odor-absorbing solutions containingwater-soluble cyclodextrin.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a stable, aqueous odor-absorbingcomposition, for use on inanimate surfaces, comprising:

A. from about 0.1% to about 5%, by weight of the composition, ofsolubilized, water-soluble, uncomplexed cyclodextrin;

B. an effective amount of a solubilized, water-soluble, antimicrobialpreservative having a water solubility of greater than about 0.3%;

I. COMPOSITION (A) CYCLODEXTRIN

As used herein, the term "cyclodextrin" includes any of the knowncyclodextrins such as unsubstituted cyclodextrins containing from six totwelve glucose units, especially, alpha-cyclodextrin, beta-cyclodextrin,gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. Thealpha-cyclodextrin consists of six glucose units, the beta-cyclodextrinconsists of seven glucose units, and the gamma-cyclodextrin consists ofeight glucose units arranged in a donut-shaped ring. The specificcoupling and conformation of the glucose units give the cyclodextrins arigid, conical molecular structure with a hollow interior of a specificvolume. The "lining" of the internal cavity is formed by hydrogen atomsand glycosidic bridging oxygen atoms; therefore, this surface is fairlyhydrophobic. The unique shape and physical-chemical properties of thecavity enable the cyclodextrin molecules to absorb (form inclusioncomplexes with) organic molecules or parts of organic molecules whichcan fit into the cavity. Many odorous molecules can fit into the cavityincluding many malodorous molecules and perfume molecules. Therefore,cyclodextrins, and especially mixtures of cyclodextrins with differentsize cavities, can be used to control odors caused by a broad spectrumof organic odoriferous materials, which may, or may not, containreactive functional groups. The complexation between cyclodextrin andodorous molecules occurs rapidly in the presence of water. However, theextent of the complex formation also depends on the polarity of theabsorbed molecules. In an aqueous solution, strongly hydrophilicmolecules (those which are highly water-soluble) are only partiallyabsorbed, if at all. Therefore, cyclodextrin does not complexeffectively with some very low molecular weight organic amines and acidswhen they are present at low levels on wet fabrics. As the water isbeing removed however, e.g., the fabric is being dried off, some lowmolecular weight organic amines and acids have more affinity and willcomplex with the cyclodextrins more readily.

The cavities within the cyclodextrin in the solution of the presentinvention should remain essentially untitled (the cyclodextrin remainsuncomplexed) while in solution, in order to allow the cyclodextrin toabsorb various odor molecules when the solution is applied to a surface.Non-derivatised (normal) beta-cyclodextrin can be used although it isnot preferred due to its low solubility, especially in compositionswhich call for a level of cyclodextrin higher than its water solubilityat room temperature (about 1.85 grams in 100 grams of water).Non-derivatised beta-cyclodextrin is further not preferred when thecomposition contains optional perfume material and a clear solution ispreferred. When non-derivatised beta-cyclodextrin is used in either ofthese situations the aqueous solution becomes cloudy and is not clear.Not to be limited by theory, it is believed that some beta-cyclodextrinand/or beta-cyclodextrin/perfume complexes solidify and/or precipitateout producing an undesirable cloudy aqueous solution.

Preferably, the odor absorbing solution of the present invention isclear. The term "clear" as defined herein means transparent ortranslucent, preferably transparent as in "water clear," when observedthrough a layer having a thickness of less than about 10 cm.

Preferably, the cyclodextrins used in the present invention are highlywater-soluble such as, alpha-cyclodextrin and derivatives thereof,gamma-cyclodextrin and derivatives thereof, derivatisedbeta-cyclodextrins, and/or mixtures thereof. The derivatives ofcyclodextrin consist mainly of molecules wherein some of the OH groupsare converted to OR groups. Cyclodextrin derivatives include, e.g.,those with short chain alkyl groups such as methylated cyclodextrins,and ethylated cyclodextrins, wherein R is a methyl or an ethyl group;those with hydroxyalkyl substituted groups, such as hydroxypropylcyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a --CH₂--CH(OH)--CH₃ or a --CH₂ CH₂ --OH group; branched cyclodextrins such asmaltose-bonded cyclodextrins; cationic cyclodextrins such as thosecontaining 2-hydroxy-3(dimethylamino)propyl ether, wherein R is CH₂--CH(OH)--CH₂ --N(CH₃)₂ which is cationic at low pH; quaternaryammonium, e.g., 2-hydroxy-3-(trimethylammonio)propyl ether chloridegroups, wherein R is CH₂ --CH(OH)--CH₂ -N+(CH₃)₃ Cl--; anioniccyclodextrins such as carboxymethyl cyclodextrins, cyclodextrinsulfates, and cyclodextrin succinylates; amphoteric cyclodextrins suchas carboxymethyl/quaternary ammonium cyclodextrins; cyclodextrinswherein at least one glucopyranose unit has a 3-6-anhydro-cyclomaltostructure, e.g., the mono-3-6-anhydrocyclodextfins, as disclosed in"Optimal Performances with Minimal Chemical Modification ofCyclodextrins", F. Diedaini-Pilard and B. Perly, The 7th InternationalCyclodextrin Symposium Abstracts, April 1994, p. 49, herein incorporatedby reference; and mixtures thereof. Other cyclodextrin derivatives aredisclosed in U.S. Pat. Nos: 3,426,011, Parmerter et al., issued Feb. 4,1969; 3,453,257; 3,453,258; 3,453,259; and 3,453,260, all in the namesof Parmerter et al., and all issued Jul. 1, 1969; 3,459,731, Gramera etal., issued Aug. 5, 1969; 3,553,191, Parmerter et al., issued Jan. 5,1971; 3,565,887, Parmerter et al., issued Feb. 23, 1971; 4,535,152,Szejtli et al., issued Aug. 13, 1985; 4,616,008, Hirai et al., issuedOct. 7, 1986; 4,678,598, Ogino et al., issued Jul. 7, 1987; 4,638,058,Brandt et al., issued Jan. 20, 1987; and 4,746,734, Tsuchiyama et al.,issued May 24, 1988; all of said patents being incorporated herein byreference.

Highly water-soluble cyclodextrins are those having water solubility ofat least about 10 g in 100 ml of water at room temperature, preferablyat least about 20 g in 100 ml of water, more preferably at least about25 g in 100 ml of water at room temperature. The availability ofsolubilized, uncomplexed cyclodextrins is essential for an effective andefficient odor control performance. Solubilized, water-solublecyclodextrin can exhibit more efficient odor control performance thannon-water-soluble cyclodextrin when deposited onto surfaces, especiallyfabric.

Examples of preferred water-soluble cyclodextrin derivatives suitablefor use herein are hydroxypropyl alpha-cyclodextrin, methylatedalpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethylbeta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkylcyclodextrin derivatives preferably have a degree of substitution offrom about 1 to about 14, more preferably from about 1.5 to about 7,wherein the total number of OK groups per cyclodextrin is defined as thedegree of substitution. Methylated cyclodextrin derivatives typicallyhave a degree of substitution of from about 1 to about 18, preferablyfrom about 3 to about 16. A known methylated beta-cyclodextrin isheptakis-2,6-di-O-methyl-β-cyclodextrin, commonly known as DIMEB, inwhich each glucose unit has about 2 methyl groups with a degree ofsubstitution of about 14. A preferred, more commercially available,methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrinhaving a degree of substitution of about 12.6. The .preferredcyclodextrins are available, e.g., from American Maize-Products Companyand Wacker Chemicals (USA), Inc.

It is also preferable to use a mixture of cyclodextrins. Such mixturesabsorb odors more broadly by complexing with a wider range ofodoriferous molecules having a wider range of molecular sizes.Preferably at least a portion of the cyclodextrins is alpha-cyclodextrinor its derivatives thereof, gamma-cyclodextrin or its derivativesthereof, and/or derivatised beta-cyclodextrin, more preferably a mixtureof alpha-cyclodextrin, or an alpha-cyclodextrin derivative, andderivatised beta-cyclodextrin, even more preferably a mixture ofderivatised alpha-cyclodextrin and derivatised beta-cyclodextrin, mostpreferably a mixture of hydroxypropyl alpha-cyclodextrin andhydroxypropyl beta-cyclodextrin, and/or a mixture of methylatedalpha-cyclodextrin and methylated beta-cyclo dextrin.

For controlling odor on fabrics, the composition is preferably used as aspray. It is preferable that the composition of the present inventioncontain low levels of cyclodextrin so that a visible stain does notappear on the fabric at normal usage levels. Preferably, the solution isvirtually not discernible when dry. Typical levels of cyclodextrin arefrom about 0.1% to about 5%, preferably from about 0.2% to about 4%,more preferably from about 0.3% to about 3%, most preferably from about0.4% to about 2%. Compositions with higher concentrations can leaveunacceptable visible stains on fabrics as the solution evaporates off ofthe fabric. This is especially a problem on thin, colored, syntheticfabrics. In order to avoid or minimize the occurrence of fabricstaining, it is preferable that the fabric be treated at a level of lessthan about 5 mg of cyclodextrin per mg of fabric, more preferably lessthan about 2 mg of cyclodextrin per mg of fabric.

Concentrated compositions can also be used in order to provide a lessexpensive product. When a concentrated product is used, i.e., when thelevel of cyclodextrin used is from about 3% to about 5%, it ispreferable to dilute the composition before treating fabrics in order toavoid staining. Preferably the cyclodextrin is diluted with about 50% toabout 2000%, more preferably with about 60% to about 1000%, mostpreferably with about 75% to about 500% by weight of the composition ofwater.

(B) ANTIMICROBIAL PRESERVATIVE

Cyclodextrin molecules are made up of varying numbers of glucose unitswhich can make them a prime breeding ground for certain microorganisms,especially when in aqueous compositions. This problem, that certainorganisms grow extremely well on cyclodextrin, has not been previouslydisclosed. This drawback can lead to the problem of storage stability ofcyclodextrin solutions for any significant length of time. Contaminationby certain microorganisms with subsequent microbial growth can result inan unsightly and/or malodorous solution. Because microbial growth incyclodextrin solutions is highly objectionable when it occurs, it ishighly preferable to include a solubilized water-soluble, antimicrobialpreservative, which is effective for inhibiting and/or regulatingmicrobial growth in order to increase storage stability of thepreferably clear, aqueous odor-absorbing solution containingwater-soluble cyclodextrin.

Typical microorganisms that can be found in cyclodextrin supplies andwhose growth can be found in the presence of cyclodextrin in aqueouscyclodextrin solutions include bacteria, e.g., Bacillus thuringiensis(cereus group) and Bacillus sphaericus; and fungi, e.g., Aspergillusustus. Bacillus sphaericus is one of the most numerous members ofBacillus species in soils. Aspergillus ustus is common in grains andflours which are raw materials to produce cyclodextrins. Microorganismssuch as Escherichia coli and Pseudomonas aeruginosa are found in somewater sources, and can be introduced during the preparation ofcyclodextrin aqueous solutions. It is preferable to use a broad spectrumpreservative, e.g., one that is effective on both bacteria (both grampositive and gram negative) and fungi. A limited spectrum preservative,e.g., one that is only effective on a single group of microorganisms,e.g., fungi, can be used in combination with a broad spectrumpreservative or other limited spectrum preservatives with complimentaryand/or supplementary activity. A mixture of broad spectrum preservativescan also be used.

Antimicrobial preservatives useful in the present invention includebiocidal compounds, i.e., substances that kill microorganisms, orbiostatic compounds, i.e., substances that inhibit and/or regulate thegrowth of microorganisms.

Preferred antimicrobial preservatives are those that are water-solubleand are effective at low levels because the organic preservatives canform inclusion complexes with the cyclodextrin molecules and competewith the malodorous molecules for the cyclodextrin cavities, thusrendering the cyclodextrins ineffective as odor controlling actives.Water-soluble preservatives useful in the present invention are thosethat have a solubility in water of at least about 0.3 g per 100 ml ofwater, i.e., greater than about 0.3% at room temperature, preferablygreater than about 0.5% at room temperature. These types ofpreservatives have a lower affinity to the cyclodextrin cavity, at leastin the aqueous phase, and are therefore more available to provideantimicrobial activity. Preservatives with a water-solubility of lessthan about 0.3% and a molecular structure that readily fits into thecyclodextrin cavity, have a greater tendency to form inclusion complexeswith the cyclodextrin molecules, thus rendering the preservative lesseffective to control microbes in the cyclodextrin solution. Therefore,many well known preservatives such as short chain alkyl esters ofp-hydroxybenzoic acid, commonly known as parabens;N-(4-chlorophenyl)-N'-(3,4-dichlorophenyl) urea, also known as3,4,4'-trichlorocarbanilide or triclocarban; 2,4,4'-trichloro-2'-hydroxydiphenyl ether, commonly known as triclosan are not preferred in thepresent invention since they are relatively ineffective when used inconjunction with cyclodextrin.

The water-soluble antimicrobial preservative in the present invention isincluded at an effective amount. The term "effective amount" as hereindefined means a level sufficient to prevent spoilage, or prevent growthof inadvertently added microorganisms, for a specific period of time. Inother words, the preservative is not being used to kill microorganismson the surface onto which the composition is deposited in order toeliminate odors produced by microorganisms. Instead, it is preferablybeing used to prevent spoilage of the cyclodextrin solution in order toincrease the shelf-life of the composition. Preferred levels ofpreservative are from about 0.0001% to about 0.5%, more preferably fromabout 0.0002% to about 0.2%, most preferably from about 0.0003% to about0.1%, by weight of the composition.

In order to reserve most of the cyclodextrins for odor control, thecyclodextrin to preservative molar ratio should be greater than about5:1, preferably greater than about 10:1, more preferably greater thanabout 50:1, even more preferably greater than about 100:1.

The preservative can be any organic preservative material which will notcause damage to fabric appearance, e.g., discoloration, coloration,bleaching. Preferred water-soluble preservatives include organic sulfurcompounds, halogenated compounds, cyclic organic nitrogen compounds, lowmolecular weight aldehydes, quaternary ammonium compounds, dehydroaceticacid, phenyl and phenoxy compounds, and mixtures thereof.

Preferred preservatives for use in the present invention are cationicand/or quaternary compounds. Such compounds include polyaminopropylbiguanide, also known as polyhexamethylene biguanide having the generalformula:

    HCl·NH.sub.2 --(CH.sub.2).sub.3 --[--(CH.sub.2).sub.3 --NH--C(=NH)--NH--C(=NH)--NH--(CH.sub.2).sub.3 --].sub.x --(CH.sub.2).sub.3 --NH--C(=NH)--NH·CN

Polyaminopropyl biguanide is a water-soluble, broad spectrumpreservative which is available as a 20% aqueous solution availableunder the trade name Cosmocil CQ® from ICI Americas, Inc., or under thetrade name Mikrokill® from Brooks, Inc.

1-(3-Chlorallyl)-3,5,7-triaza-1-azoniaadamantane chloride, available,e.g., under the trade name Dowicil 200 from Dow Chemical, is aneffective quaternary ammonium preservative; it is freely soluble inwater; however, it has the tendency to discolor (yellow), therefore itis not highly preferred.

Mixtures of the preferred quaternary ammonium compounds can also be usedas the preservative in the present invention.

When quaternary ammonium compounds are used as the preservative in thepresent invention, they are typically present at a level of from about0.005% to about 0.2%, preferably from about 0.01% to about 0.1%, byweight of the composition.

(6) Dehydroacetic Acid

A preferred preservative for use in the present invention isdehydroacetic acid. Dehydroacetic acid is a broad spectrum preservativepreferably in the form of a sodium or a potassium salt so that it iswater-soluble. This preservative acts more as a biostatic preservativethan a biocidal preservative. When dehydroacetic acid is used as thepreservative it is typically used at a level of from about 0.005% toabout 0.2%, preferably from about 0.008% to about 0.1%, more preferablyfrom about 0.01% to about 0.05%, by weight of the composition.

(7) Phenyl and Phenoxy Compounds

Some non-limiting examples of phenyl and phenoxy compounds suitable foruse in the present invention are:

4,4'-diamidino-α,ω-diphenoxypropane diisethionate, commonly known aspropamidine isethionate, with water solubility of about 16%; and4,4'-diamidino-α,ω-diphenoxyhexane diisethionate, commonly known ashexamidine isethionate. Typical effective level of these salts is about0.0002% to about 0.05%.

Other examples are benzyl alcohol, with a water solubility of about 4%;2-phenylethanol, with a water solubility of about 2%; and2-phenoxyethanol, with a water solubility of about 2.67%; typicaleffective level of these phenyl and phenoxy alcohol is from about 0.1%to about 0.5%, by weight of the composition.

(8) Mixtures Thereof

The preservatives of the present invention can be used in mixtures inorder to control a broad range of microorganisms.

Bacteriostatic effects can sometimes be obtained for aqueouscompositions by adjusting the composition pH to an acid pH, e.g., lessthan about pH 4, preferably less than about pH 3, or a basic pH, e.g.,greater than about 10, preferably greater than about 11. Low pH formicrobial control is not a preferred approach in the present inventionbecause the low pH can cause chemical degradation of the cyclodextrins.High pH for microbial control is also not preferred because at highpH's, e.g., greater than about 10, preferably greater than about 11, thecyclodextrins can be ionized and their ability to complex with organicmaterials is reduced. Therefore, aqueous compositions of the presentinvention should have a pH of from about 3 to about 10, preferably fromabout 4 to about 8, more preferably from about 4.5 to about 7.

As stated above, it is preferable to use the preservative at aneffective amount, as defined herein above. Optionally however, thepreservative can be used at a level which provides an antimicrobialeffect on the treated fabrics. Even when the preservative is used inthis capacity, it is preferable that an effective level of cyclodextrinmolecules remain uncomplexed in the solution in order to provide theodor absorbing benefit.

(C) PERFUME

The odor absorbing composition of the present invention can alsooptionally provide a "scent signal" in the form of a pleasant odor whichsignals the removal of malodor from fabrics. The scent signal isdesigned to provide a fleeting perfume scent, and is not designed to beoverwhelming or to be used as an odor masking ingredient. When perfumeis added as a scent signal, it is added only at very low levels, e.g.,from about 0% to about 0.5%, preferably from about 0.003% to about 0.3%,more preferably from about 0.005% to about 0.2%, by weight of thecomposition.

Perfume can also be added as a more intense odor in product and onsurfaces. When stronger levels of perfume are preferred, relativelyhigher levels of perfume can be added. It is essential, however, thatthe perfume be added at a level wherein even if all of the perfume inthe composition were to complex with the cyclodextrin molecules, therewill still be an effective level of uncomplexed cyclodextrin moleculespresent in the solution to provide adequate odor control. In order toreserve an effective amount of cyclodextrin molecules for odor control,perfume is typically present at a level wherein less than about 90% ofthe cyclodextrin complexes with the perfume, preferably less than about50% of the cyclodextrin complexes with the perfume, more preferably,less than about 30% of the cyclodextrin complexes with the perfume, andmost preferably, less than about 10% of the cyclodextrin complexes withthe perfume. The cyclodextrin to perfume weight ratio should be greaterthan about 8:1, preferably greater than about 10:1, more preferablygreater than about 20:1, even more preferably greater than 40:1 and mostpreferably greater than about 70:1.

Any type of perfume can be incorporated into the composition of thepresent invention. There are however, perfume characteristics which arepreferred for use on fabrics in order to provide a fresh fabricimpression and perfume characteristics which are preferred for householduse.

Preferably, at least about 25%, more preferably at least about 50%, mostpreferably at least about 75%, by weight of the perfume is composed offragrance material selected from the group consisting of aromatic andaliphatic esters having molecular weights from about 130 to about 250;aliphatic and aromatic alcohols having molecular weights from about 90to about 240; aliphatic ketones having molecular weights from about 150to about 260; aromatic ketones having molecular weights from about 150to about 270; aromatic and aliphatic lactones having molecular weightsfrom about 130 to about 290; aliphatic aldehydes having molecularweights from about 140 to about 200; aromatic aldehydes having molecularweights from about 90 to about 230; aliphatic and aromatic ethers havingmolecular weights from about 150 to about 270; and condensation productsof aldehydes and amines having molecular weights from about 180 to about320; and essentially free from nitromusks and halogenated flagrancematerials.

and mixtures thereof.

When high initial perfume odor impact on fabrics is desired, it is alsopreferable to select a perfume containing perfume ingredients which arenot too hydrophobic. The less hydrophobic perfume ingredients are moresoluble in water, and are more available in the odor absorbingcomposition. The degree of hydrophobicity of a perfume ingredient can becorrelated with its octanol/water partitioning coefficient P. Theoctanol/water partitioning coefficient of a perfume ingredient is theratio between its equilibrium concentration in octanol and in water. Aperfume ingredient with a greater partitioning coefficient P is morehydrophobic. Conversely, a perfume ingredient with a smallerpartitioning coefficient P is more hydrophilic. The preferred perfumeingredients of this invention have an octanol/water partitioningcoefficient P of about 1,000 or smaller. Since the partitioningcoefficients of the perfume ingredients normally have high values, theyare more conveniently given in the form of their logarithm to the base10, logP. Thus the perfume ingredients of this invention have logP ofabout 3 or smaller.

The logP of many perfume ingredients has been reported; for example, thePomona 92 database, available from Daylight Chemical InformationSystems, Inc. (Daylight CIS), Irvine, Calif., contains many, along withcitations to the original literature. However, the logP values are mostconveniently calculated by the "CLOGP" program, also available fromDaylight CIS. This program also lists experimental logP values when theyare available in the Pomona 92 database. The "calculated IogP" (ClogP)is determined by the fragment approach of Hansch and Leo (cf., A. Leo,in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens,J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990,incorporated herein by reference). The fragment approach is based on thechemical structure of each perfume ingredient, and takes into accountthe numbers and types of atoms, the atom connectivity, and chemicalbonding. The ClogP values, which are the most reliable and widely usedestimates for this physicochemical property, are used instead of theexperimental logP values in the selection of perfume ingredients whichare useful in the present invention.

Non-limiting examples of perfume ingredients which have ClogP values ofabout 3 or smaller are benzaldehyde, benzyl acetate, cis-3-hexenylacetate, coumarin, dihydromyrcenol, dimethyl benzyl carbinyl acetate,ethyl vanillin, eucalyptol, eugenol, iso eugenol, flor acetate,geraniol, hydroxycitronellal, koavone, linalool, methyl anthranilate,methyl beta naphthyl ketone, methyl dihydro jasmonate, nerol,nonalactone, phenyl ethyl acetate, phenyl ethyl alcohol, alphaterpineol, beta terpineol, vanillin, and mixtures thereof.

When hydrophilic perfume is desired, at least about 25% by weight of theperfume, more preferably about 50%, most preferably about 75%, iscomposed of perfume ingredients having a ClogP of about 3 or smaller.

Cyclodextrin molecules are known for their ability to form complexeswith perfume ingredients and have typically been taught as a perfumecarrier. The prior art teaches the use of drier-added fabric softenersheets containing high levels of cyclodextrin/perfume complexes whereinthe fabrics treated with this solid cyclodextrin complex release perfumewhen the fabrics are rewetted. The art also teaches thatcyclodextrin/perfume complexes used in aqueous rinse-added fabricsoftener compositions must be protected with a hydrophobic wax coatingso the cyclodextrin/perfume complexes will not decompose due to thepresence of water. See U.S. Pat. Nos. 5,102,564 Gardlik et al., issuedApr. 7, 1992; 5,234,610 Gardlik et al., issued Aug. 10, 1993; 5,234,611Trinh, et al., issued Aug. 10, 1993. It is therefore highly surprisingand unexpected to find that fabrics treated with the aqueouscompositions of the present invention, which contain low levels ofuncomplexed cyclodextrin and even lower levels of perfume, also exhibitperfume release upon rewetting. This phenomenon creates a benefit inthat fabrics treated with the composition of the present invention willthus remain fresh longer, via a perfume release, when said fabrics arerewetted, such as when the wearer perspires.

(D) CARRIER

Aqueous solutions are preferred for odor control. The dilute aqueoussolution provides the maximum separation of cyclodextrin molecules onthe fabric and thereby maximizes the chance that an odor molecule willinteract with a cyclodextrin molecule.

The preferred carrier of the present invention is water. The water whichis used can be distilled, deionized, or tap water. Water not only servesas the liquid carrier for the cyclodextrins, but it also facilitates thecomplexation reaction between the cyclodextrin molecules and anymalodorous molecules that are on the fabric when it is treated. It hasrecently been discovered that water has an unexpected odor controllingeffect of its own. It has been discovered that the intensity of the odorgenerated by some polar, low molecular weight organic amines, acids, andmercaptans is reduced when the odor-contaminated fabrics are treatedwith an aqueous solution. Not to be bound by theory, it is believed thatwater solubilizes and depresses the vapor pressure of these polar, lowmolecular weight organic molecules, thus reducing their odor intensity.

(E) OPTIONAL INGREDIENTS

The composition of the present invention can optionally contain adjunctodor-controlling materials, chelating agents, solubilizing aids,antifoaming agents, defoaming agents, antistatic agents, insect and mothrepelling agents, colorants, especially bluing agents, antioxidants, andmixtures thereof. Incorporating adjunct odor-controlling materials canenhance the capacity of the cyclodextrin to control odors as well asbroaden the range of odor types and molecule sizes which can becontrolled. Such materials include, for example, metallic salts,water-soluble cationic and anionic polymers, water-soluble bicarbonatesalts, zeolites, activated carbon, and mixtures thereof.

(1) Metallic Salt

Optionally, but highly preferred, the present invention can includemetallic salts for added odor absorption and/or antimicrobial benefitfor the cyclodextrin solution. The metallic salts are selected from thegroup consisting of copper salts, zinc salts, and mixtures thereof.

Copper salts have some antimicrobial benefits. Specifically, cupricabietate acts as a fungicide, copper acetate acts as a mildew inhibitor,cupric chloride acts as a fungicide, copper tactate acts as a fungicide,and copper sulfate acts as a germicide. Copper salts also possess somemalodor control abilities. See U.S. Pat. No. 3,172,817, Leupold, et at.,which discloses deodorizing Compositions for treating disposablearticles, comprising at least slightly water-soluble salts ofacylacetone, including copper salts and zinc salts; said patents areincorporated herein by reference.

The preferred salts possess malodor control abilities. Zinc has beenused most often for its ability to ameliorate malodor, e.g., in mouthwash products, as disclosed in U.S. Pat. Nos. 4,325,939, issued Apr. 20,1982 and 4,469,674, issued Sept. 4, 1983, to N. B. Shah, et al., all ofwhich are incorporated herein by reference. Highly-ionized and solublezinc salts such as zinc chloride, provide the best source of zinc ions.Zinc borate functions as a fungistat and a mildew inhibitor, zinccaprylate functions as a fungicide, zinc chloride provides antisepticand deodorant benefits, zinc ricinoleate functions as a fungicide, zincsulfate heptahydrate functions as a fungicide and zinc undecylenatefunctions as a fungistat.

Preferably the metallic salts are water-soluble zinc salts, copper saltsor mixtures thereof, and more preferably zinc salts, especially ZnCl₂.These salts are preferably present in the present invention primarily toabsorb amine and sulfur-containing compounds that have molecular sizestoo small to be effectively complexed with the cyclodextrin molecules.Low molecular weight sulfur-containing materials, e.g., sulfide andmercaptans, are components of many types of malodors, e.g., food odors(garlic, onion), body/perspiration odor, breath odor, etc. Low molecularweight amines are also components of many malodors, e.g., food odors,body odors, urine, etc.

When metallic salts are added to the composition of the presentinvention they are typically present at a level of from about 0.1% toabout 10%, preferably from about 0.2% to about 7%, more preferably fromabout 0.3% to about 5% by weight of the composition. When zinc salts areused as the metallic salt, and a clear solution is desired, it ispreferable that the pH of the solution is adjusted to less than about 7,more preferably less than about 6, most preferably less than about 5, inorder to keep the solution clear.

(2) Water-Soluble Polymers

Some water-soluble polymers, e.g., water-soluble cationic polymer andwater-soluble anionic polymers can be used in the composition of thepresent invention to provide additional odor control benefits.

(a) Cationic Polymers, e.g., Polyamines

Water-soluble cationic polymers, e.g., those containing aminofunctionalities, amido functionalities, and mixtures thereof, are usefulin the present invention to control certain acid-type odors.

(b) Anionic Polymers, e.g., Polyacrylic Acid

Water-soluble anionic polymers, e.g., polyacrylic acids and theirwater-soluble salts are useful in the present invention to controlcertain amine-type odors. Preferred polyacrylic acids and their alkalimetal salts have an average molecular weight of less than about 20,000,more preferably less than 5,000. Polymers containing sulfonic acidgroups, phosphoric acid groups, phosphonic acid groups, and theirwater-soluble salts, and mixtures thereof, and mixtures with carboxylicacid and carboxylate groups, are also suitable.

Water-soluble polymers containing both cationic and anionicfunctionalities are also suitable. Examples of these polymers are givenin U.S. Pat. No. 4,909,986, issued Mar. 20, 1990 to N. Kobayashi and A.Kawazoe, incorporated herein by reference. Another example ofwater-soluble polymers containing both cationic and anionicfunctionalities is a copolymer of dimethyldiallyl ammonium chloride andacrylic acid, commercially available under the trade name Merquat 280®from Calgon.

(3) Low Molecular Weight Polyols

Low molecular weight polyols with relatively high boiling points, ascompared to water, such as ethylene glycol, propylene glycol and/orglycerol are preferred optional ingredients for improving odor controlperformance of the composition of the present invention. Not to be boundby theory, it is believed that the incorporation of a small amount oflow molecular weight glycols into the composition of the presentinvention enhances the formation of the cyclodextrin inclusion complexesas the fabric dries.

It is believed that the polyols ability to remain on the fabric for alonger period of time than water, as the fabric dries, allows them toform ternary complexes with the cyclodextrin and some malodorousmolecules. The addition of the glycols is believed to fill up void spacein the cyclodextrin cavity that is unable to be filled by some malodormolecules of relatively smaller sizes. Preferably the glycol used isethylene glycol, and/or propylene glycol. Cyclodextrins prepared byprocesses that result in a level of such polyols are highly desirable,since they can be used without removal of the polyols.

When glycols are added to the composition of the present invention thepreferred weight ratio of low molecular weight polyol to cyclodextrin isfrom about 1:1,000 to about 20:100, more preferably from about 3:1,000to about 15:100, even more preferably from about 5:1,000 to about10:100, and most preferably from about 1:100 to about 7:100.

(4) Soluble Carbonate and/or Bicarbonate Salts

Water-soluble alkali metal carbonate and/or bicarbonate salts, such assodium bicarbonate, potassium bicarbonate, potassium carbonate, cesiumcarbonate, sodium carbonate, and mixtures thereof can be added to thecomposition of the present invention in order to help to control certainacid-type odors. Preferred salts are sodium carbonate monohydrate,potassium carbonate, sodium bicarbonate, potassium bicarbonate, andmixtures thereof. When these salts are added to the composition of thepresent invention, they are typically present at a level of from about0.1% to about 5%, preferably from about 0.2% to about 3%, morepreferably from about 0.3% to about 2%, by weight of the composition.When these salts are added to the composition of the present inventionit is preferably that incompatible metal salts not be present in theinvention. Preferably, when these salts are used the composition shouldbe essentially free of zinc and other incompatible metal ions, e.g., Ca,Fe, Ba, etc., which form water-insoluble salts.

(5) Chelating Agents

Some amine/acid chelating agents such as ethylenediaminetetraacetic acid(EDTA) can optionally be added to the composition of the presentinvention in order to enhance the activity of the water-soluble,antimicrobial preservative. When a chelating agent is added to thecomposition of the present invention, it is typically present at a levelof from about 0.01% to about 0.3%, preferably from about 0.05% to about0.2%. It is important that the composition of the present invention beessentially free of any added metal ions that can be chelated by anychelating agent that is added to the composition of the presentinvention because such metal ions complex with, and deactivate, thechelating agents.

(6) Antistatic Agents

The composition of the present invention can optionally contain aneffective amount of antistatic agent to provide the treated clothes within-wear static. Preferred antistatic agents are those that are watersoluble in at least effective amount, such that the composition remainsa clear solution. Examples of these antistatic agents are monoalkylcationic quaternary ammonium compounds, e.g., mono(C₁₀ -C₁₄alkyl)trimethyl ammonium halide, such as monolauryl trimethyl ammoniumchloride, hydroxycetyl hydroxyethyl dimethyl ammonium chloride,available under the trade name Dehyquart E® from Henkel, and ethylbis(polyethoxy ethanol) alkylammonium ethylsulfate, available under thetrade name Variquat 66® from Witco Corp., polyethylene glycols,polymeric quaternary ammonium salts, such as polymers conforming to thegeneral formula:

available under the trade name Mirapol AD-1® from Rhone-Poulenc,quaternized polyethyleneimines,vinylpyrrolidone/methacrylamidopropyltrimethylammonium chloridecopolymer, available under the trade name Gafquat HS-100® from GAF;triethonium hydrolyzed collagen ethosulfate, available under the tradename Quat-Pro E® from Maybrook; and mixtures thereof.

It is preferred that a no foaming, or low foaming, agent is used, toavoid foam formation during fabric treatment. It is also preferred thatpolyethoxylated agents such as polyethylene glycol or Variquat 66® arenot used when alpha-cyclodextrin is used. The polyethoxylate groups havea strong affinity to, and readily complex with, alpha-cyclodextrin whichin turn depletes the uncomplexed cyclodextrin available for odorcontrol.

When an antistatic agent is used it is typically present at a level offrom about 0.05% to about 10%, preferably from about 0.1% to about 5%,more preferably from about 0.3% to about 3%, by weight of thecomposition.

(7) Insect and/or Moth Repelling Agent

The composition of the present invention can optionally contain aneffective amount of insect and/or moth repelling agents. Typical insectand moth repelling agents are pheromones, such as anti-aggregationpheromones, and other natural and/or synthetic ingredients. Preferredinsect and moth repellent agents useful in the composition of thepresent invention are perfume ingredients, such as citronellol,citranellal, citral, linalool, cedar extract, geranium oil, sandalwoodoil, 2-(diethylphenoxy)ethanol, etc. Other examples of insect and/ormoth repellents useful in the composition of the present invention aredisclosed in U.S. Pat. Nos. 4,449,987, 4,693,890, 4,696,676, 4,933,371,5,196,200, and in "Semio Activity of Flavor and Fragrance Molecules onVarious Insect Species", B. D. Mookherjee et al., published in BioactiveVolatile Compounds from Plants, ASC Symposium Series 525, R. Teranishi,R. G. Buttery, and H. Sugisawa, 1993, pp. 35-48, all of said patents andpublications being incorporated herein by reference. When an insectand/or moth repellent is used it is typically present at a level of fromabout 0.005% to about 3%, by weight of the composition.

(8) Solubilizing Aid

The odor absorbing composition of the present invention can alsooptionally contain a solubilizing aid to solubilize any excesshydrophobic organic materials, e.g., perfume, insect repelling agent,antioxidant, etc., that are not readily soluble in the composition, toform a clear solution. A suitable solubilizing aid is surfactant,preferably no-foaming or low-foaming surfactant. Suitable surfactantsare nonionic surfactants, anionic surfactants, cationic surfactants,amphoteric surfactants, zwitterionic surfactants, and mixtures thereof.Suitable surfactants can be emulsifiers and/or detersive surfactants.Mixtures of emulsifiers and detersive surfactants are also preferred.When a surfactant containing one, or more, aliphatic alkyl group isused, it is preferred that it contain relatively short alkyl chains offrom about 5 to about 14 carbon atoms. Preferred nonionic surfactantsare polyethylene glycol-polypropylene glycol block copolymers, such asPluronic® and Pluronic R® surfactants from BASF; Tetronic® and TetronicR® surfactants from BASF, ethoxylated branched aliphatic diols such asSurfynol® surfactants from Air Products; ethoxylated alkyl phenols, suchas Igepal® surfactants from Rhone-Poulenc; ethoxylated aliphaticalcohols and carboxylic acids; polyethylene glycol diesters of fattyacids; fatty acid esters of ethoxylated sorbitans; and mixtures thereof.Preferred anionic surfactants are dialkyl sulfosuccinate,alkylarylsulfonate, fatty alcohol sulfate, paraffin sulfonate, alkylsarcosinate, alkyl isethionate salts having suitable cations, e.g.,sodium, potassium, alkanol ammonium, etc., and mixtures thereof.Preferred amphoteric surfactants are the betaines. It is preferred thatthe surfactant have good wetting properties. Also preferred aresurfactants that have the hydrophilic groups situated betweenhydrophobic chains, such as Pluronic R® surfactants, Surfynolsurfactants, polyethylene glycol diesters of fatty acids, fatty acidesters of ethoxylated sorbitans, dialkyl sulfosuccinate, di(C₈ -C₁₂alkyl)di(C₁ -C₂ alkyl)ammonium halides, and mixtures thereof; orsurfactants that have the hydrophobic chains situated betweenhydrophilic groups, such as Pluronic surfactants; and mixtures thereof.Mixtures of these surfactants and other types of surfactants are alsopreferred to form no-foaming or low-foaming solubilizing agents.Polyalkylene glycol can be used as a defoaming agent in combination withthe solubilizing agents.

If solubilizing agent is used in the present compositions, it istypically used at a level of from about 0.05% to about 1% by weight ofthe composition, more preferably from about 0.05% to about 0.3%.

(9) Additional Odor Absorbers

When the clarity of the solution is not needed, and the solution is notsprayed on fabrics, other optional odor absorbing materials, e.g.,zeolites and/or activated carbon, can also be used.

(a) Zeolites

A preferred class of zeolites is characterized as "intermediate"silicate/aluminate zeolites. The intermediate zeolites are characterizedby SiO₂ /AlO₂ molar ratios of less than about 10. Preferably the molarratio of SiO₂ /AlO₂ ranges from about 2 to about 10. The intermediatezeolites have an advantage over the "high" zeolites. The intermediatezeolites have a higher affinity for amine-type odors, they are moreweight efficient for odor absorption because they have a larger surfacearea, and they are more moisture tolerant and retain more of their odorabsorbing capacity in water than the high zeolites. A wide variety ofintermediate zeolites suitable for use herein are commercially availableas Valfor® CP301-68, Valfor® 300-63, Valfor® CP300-35, and Valfor®CP300-56, available from PQ Corporation, and the CBV100® series ofzeolites from Conteka.

Zeolite materials marketed under the trade name Abscents® andSmellrite®, available from The Union Carbide Corporation and UOP arealso preferred. These materials are typically available as a whitepowder in the 3-5 micron particle size range. Such materials arepreferred over the intermediate zeolites for control ofsulfur-containing odors, e.g., thiols, mercaptans.

(b) Activated Carbon

The carbon material suitable for use in the present invention is thematerial well known in commercial practice as an absorbent for organicmolecules and/or for air purification purposes. Often, such carbonmaterial is referred to as "activated" carbon or "activated" charcoal.Such carbon is available from commercial sources under such trade namesas; Calgon-Type CPG®; Type PCB®; Type SGL®; Type CAL®; and Type OL®.

It is preferred that no, or essentially no, volatile low molecularweight monohydric alcohols such as ethanol and/or isopropanol areintentionally added to the composition of the present invention sincethese volatile organic compounds will contribute both to flammabilityproblems and environmental pollution problems. If small amounts of lowmolecular weight monohydric alcohols are present in the composition ofthe present invention due to the addition of these alcohols to suchthings as perfumes and as stabilizers for some preservatives, it ispreferable that the level of monohydric alcohol be less than about 5%,preferably less than about 3%, more preferably less than about 1%.

(10) Colorant

Colorants and dyes, especially bluing agents, can be optionally added tothe odor absorbing compositions for visual appeal and performanceimpression. When colorants are used, they are used at extremely lowlevels to avoid fabric staining. Preferred colorants for use in thepresent compositions are highly water-soluble dyes, e.g., Liquitint®dyes available from Milliken Chemical Co. Non-limiting examples ofsuitable dyes are, Liquitint Blue lIP®, Liquitint Blue 65®, LiquitintPatent Blue®, Liquitint Royal Blue®, Liquitint Experimental Yellow8949-43®, Liquitint Green HMC®, Liquitint Yellow II®, and mixturesthereof, preferably Liquitint Blue HP®, Liquitint Blue 65®, LiquitintPatent Blue®, Liquitint Royal Blue®, Liquitint Experimental Yellow8949-43®, and mixtures thereof.

II. ARTICLE OF MANUFACTURE

The composition of the present invention can also be used in an articleof manufacture comprising said composition plus a spray dispenser. Whenthe commercial embodiment of the article of manufacture is used, it isoptional, but preferable, to include the preservative. Therefore, themost basic article of manufacture comprises uncomplexed cyclodextrin, acarrier, and a spray dispenser.

SPRAY DISPENSER

The article of manufacture herein comprises a spray dispenser. Thecyclodextrin composition is placed into a spray dispenser in order to bedistributed onto the fabric. Said spray dispenser is any of the manuallyactivated means for producing a spray of liquid droplets as is known inthe art, e.g. trigger-type, pump-type, non-aerosol self-pressurized, andaerosol-type spray means. The spray dispenser herein does not includethose that will substantially foam the clear, aqueous odor absorbingcomposition. It is preferred that at least about 80%, more preferably,at least about 90% of the droplets have a particle size of larger thanabout 30 μm

The spray dispenser can be an aerosol dispenser. Said aerosol dispensercomprises a container which can be constructed of any of theconventional materials employed in fabricating aerosol containers. Thedispenser must be capable of withstanding internal pressure in the rangeof from about 20 to about 110 p.s.i.g., more preferably from about 20 toabout 70 p.s.i.g. The one important requirement concerning the dispenseris that it be provided with a valve member which will permit the clear,aqueous odor absorbing composition contained in the dispenser to bedispensed in the form of a spray of very fine, or finely divided,particles or droplets. The aerosol dispenser utilizes a pressurizedsealed container from which the clear, aqueous odor-absorbingcomposition is dispensed through a special actuator/valve assembly underpressure. The aerosol dispenser is pressurized by incorporating thereina gaseous component generally known as a propellant. Common aerosolpropellants, e.g., gaseous hydrocarbons such as isobutane, and mixedhalogenated hydrocarbons, are not preferred. Halogenated hydrocarbonpropellants such as chlorofluoro hydrocarbons have been alleged tocontribute to environmental problems. Hydrocarbon propellants can formcomplexes with the cyclodextrin molecules thereby reducing theavailability of uncomplexed cyclodextrin molecules for odor absorption.Preferred propellants are compressed air, nitrogen, inert gases, carbondioxide, etc. A more complete description of commercially availableaerosol-spray dispensers appears in U.S. Pat. Nos.: 3,436,772, Stebbins,issued Apr. 8, 1969; and 3,600,325, Kaufman et al., issued Aug. 17,1971; both of said references are incorporated herein by reference.

Preferably the spray dispenser can be a self-pressurized non-aerosolcontainer having a convoluted liner and an elastomeric sleeve. Saidself-pressurized dispenser comprises a liner/sleeve assembly containinga thin, flexible radially expandable convoluted plastic liner of fromabout 0.010 to about 0.020 inch thick, inside an essentially cylindricalelastomeric sleeve. The liner/sleeve is capable of holding a substantialquantity of odor-absorbing fluid product and of causing said product tobe dispensed. A more complete description of self-pressurized spraydispensers can be found in U.S. Pat. Nos. 5,111,971, Winer, issued May12, 1992, and 5,232,126, Winer, issued Aug. 3, 1993; both of saidreferences are herein incorporated by reference. Another type of aerosolspray dispenser is one wherein a barrier separates the odor absorbingcomposition from the propellant (preferably compressed air or nitrogen),as is disclosed in U.S. Pat. No. 4,260,110, issued Apr. 7, 1981,incorporated herein by reference. Such a dispenser is available from EPSpray Systems, East Hanover, N.J.

More preferably, the spray dispenser is a non-aerosol, manuallyactivated, pump-spray dispenser. Said pump-spray dispenser comprises acontainer and a pump mechanism which securely screws or snaps onto thecontainer. The container comprises a vessel for containing the aqueousodor-absorbing composition to be dispensed.

The pump mechanism comprises a pump chamber of substantially fixedvolume, having an opening at the inner end thereof. Within the pumpchamber is located a pump stem having a piston on the end thereofdisposed for reciprocal motion in the pump chamber. The pump stem has apassageway there through with a dispensing outlet at the outer end ofthe passageway and an axial inlet port located inwardly thereof.

The container and the pump mechanism can be constructed of anyconventional material employed in fabricating pump-spray dispensers,including, but not limited to: polyethylene; polypropylene;polyethyleneterephthalate; blends of polyethylene, vinyl acetate, andrubber elastomer. A preferred container is made of clear, e.g.,polyethylene terephthalate. Other materials can include stainless steel.A more complete disclosure of commercially available dispensing devicesappears in: U.S. Pat. Nos.: 4,895,279, Schultz, issued Jan. 23, 1990;4,735,347, Schultz et al., issued Apr. 5, 1988; and 4,274,560, Carter,issued Jun. 23, 1981; all of said references are herein incorporated byreference.

Most preferably, the spray dispenser is a manually activatedtrigger-spray dispenser. Said trigger-spray dispenser comprises acontainer and a trigger both of which can be constructed of any of theconventional material employed in fabricating trigger-spray dispensers,including, but not limited to: polyethylene; polypropylene; polyacetal;polycarbonate; polyethyleneterephthalate; polyvinyl chloride;polystyrene; blends of polyethylene, vinyl acetate, and rubberelastomer. Other materials can include stainless steel and glass. Apreferred container is made of clear, e.g. polyethylene terephthalate.The trigger-spray dispenser does not incorporate a propellant gas intothe odor-absorbing composition, and preferably it does not include thosethat will foam the odor-absorbing composition. The trigger-spraydispenser herein is typically one which acts upon a discrete amount ofthe odor-absorbing composition itself, typically by means of a piston ora collapsing bellows that displaces the composition through a nozzle tocreate a spray of thin liquid. Said trigger-spray dispenser typicallycomprises a pump chamber having either a piston or bellows which ismovable through a limited stroke response to the trigger for varying thevolume of said pump chamber. This pump chamber or bellows chambercollects and holds the product for dispensing. The trigger spraydispenser typically has an outlet check valve for blocking communicationand flow of fluid through the nozzle and is responsive to the pressureinside the chamber. For the piston type trigger sprayers, as the triggeris compressed, it acts on the fluid in the chamber and the spring,increasing the pressure on the fluid. For the bellows spray dispenser,as the bellows is compressed, the pressure increases on the fluid. Theincrease in fluid pressure in either trigger spray dispenser acts toopen the top outlet check valve. The top valve allows the product to beforced through the swirl chamber and out the nozzle to form a dischargepattern. An adjustable nozzle cap can be used to vary the pattern of thefluid dispensed.

For the piston spray dispenser, as the trigger is released, the springacts on the piston to return it to its original position. For thebellows spray dispenser, the bellows acts as the spring to return to itsoriginal position. This action causes a vacuum in the chamber. Theresponding fluid acts to close the outlet valve while opening the inletvalve drawing product up to the chamber from the reservoir.
